The result is that and down in the` Water and clothes. When the pounder head movesV downwardly obviously a stream of air and Vwater will be forced through the clothes and upwardly through the ball vvalves and perforated nipples 45. When the head is raised theball valve will be closed and bya vacuum action fresh Water and air will be forcedvthrough the clothes in the same direction.
